Hang after Apply Recommended Cloudflare Settings for WordPress

Can you share more details? There was a bad plugin release (v3.8.1), so if that is the version of the plugin you have please upgrade to the latest.

Hi,

Using the latest version (3.8.2).

After clicking the Apply button just see the circling animation (replacing the apply button), but the process never completes, in another word, “hangs”. Can click on Settings or Analytics and that action takes to the correct pages. When I click on Home after that the “hang” the Apply button appears again and the hanging animated circle is no longer visible.

I’ve seen errors in the browser console at some point, which went away after I reloaded the page with caching disabled (force reload).

Do you see anything in your browser console after you force the page to reload?

I see two errors in the console even before clinking on the Apply button:

compiled.js?ver=3.8.3:35 PATCH https://mydomain.com/wp-admin/admin-ajax.php?action=cloudflare_proxy 403

Uncaught SyntaxError: Unexpected token < in JSON at position 0

at d.r.emit (compiled.js?ver=3.8.3:35)

P.S. I have updated to 3.8.3

403 means the call may be blocked by a security plugin or a server firewall, then. Can you eliminate these and retest?

@galbaras that you for your suggestion. We have done many tests including different hosts and all sites show the same 403 errors. Would you have any other pointers?

To me, this looks like the call to admin-ajax.php is being blocked by your system (web server, firewall or WordPress plugin). When this happens to me, I do the following:

1. Disable my security plugin and ensure its rules are removed from .htaccess – If the problem goes away, I look at the plugin configuration.
2. Contact my hosting provider and ask to check mod_security logs and/or firewall logs – My hosting provider sometimes tightens security, so if it’s not my site, they can relax the rules for me and the problem goes away.
